Is this homework? What have you done so far?

hey, so far i have created this x=[-9:.1:9]; >> norm=normpdf(x,0,1) I have created the normal distribution function. So I scaled the x to be from -9 to 9 and I put in the parameter

Trying looking up the documentation for the bar function. I think that, and your norm vector are all you need.

but I have to use the cumsum function.

How do you get a CDF? Add up the PDF. What does cumsum do? Add up a vector. Where is your PDF? In a vector named norm. How do you add up a vector? cumsum.

Just play around with it. You have all the tools you need.
